And she does this to try and get out of going to bed

At her house she has a room but her mom doesn't put her foot down and make her sleep in her room mainly her mom does it for own benefit not my step daughter's benefit now she sleeps by herself in mine and my boyfriend's living room on the twin bed we kind of had to make her sleep by herself because we want her to be able to sleep alone so far she's doing better with us her mom turned her bedroom into a storage room

Does she have nightmares I slept with my mom til I was like 12. I still have nightmares maybe try dream catchers or try to figure out why she doesn't want to sleep alone
